The partial pressure of oxygen decreases as altitude increases, the preoperative chronic hypoxemia (CH) may have a plausible clinical impact. Risk factors for postoperative serious adverse events (pSAEs) in patients living in high altitudes during primary hip arthroplasty (HA) are not clear.This is an observational study embracing patients from January 1, 2011 to December 31, 2015 at Yan'an Hos...

To determine the magnitude, duration, and associated factors of perioperative changes in pulmonary function, we retrospectively reviewed the medical records of 145 patients who required preoperative mechanical ventilation for acute respiratory failure before undergoing 200 surgical procedures. Patients were grouped into five pulmonary diagnostic categories: (1) adult respiratory distress syndro...

Background: Hypoxemia is a frequent complication after general anesthesia. It usually takes longer to recover in individuals with respiratory problems. Bakers may suffer from respiratory problems such as asthma. The objective of this study was to compare the occurrence of hypoxemia and duration of supplemental oxygen administration during recovery from general anesthesia in bakers and smokers. ...

BACKGROUND Perioperative respiratory complications after adenotonsillectomy (T&A) are common and have been described to occur more frequently in children below 3 years of age, those with cranio-facial abnormalities, Down syndrome, obstructive sleep apnea, morbid obesity, and failure to thrive. AIMS To investigate the association between awake vs deep tracheal extubation and perioperative resp...

BACKGROUND We observed an increased rate of pulmonary complications (hypoxemia, pulmonary edema, re-intubation) in some patients after posterior spinal fusion, though standardized intraoperative volume regimens for major surgery were used. Therefore, we focused on the effects of two different standardized fluid regimens (liberal vs. conventional) as well as on two different types of postoperati...

of 100% oxygen during induction and emergence is standard practice for the vast majority of anesthetists, our study reflects the impact of high intraoperative inspired oxygen in actual practice. The use of 100% oxygen for induction and emergence also likely had minimal effect on our results because the degree of atelectasis induced by administration of 100% oxygen for only a few minutes is rela...

In adult population after bicuspid aortic valve, atrial septal defect (ASD) is the most common congenital acyanotic heart disease, with high prevalence in females. Large ASD pulmonary hypertension (PAH) posted for non-cardiac surgery poses a challenge to anaesthesiologists because intraoperative hypercarbia, hypoxemia, and hyperthermia can result increased vascular resistance (PVR), which shunt...

BACKGROUND Early acquisition of critical competencies by novice anesthesiology residents is essential for patient safety, but traditional training methods may be insufficient. The purpose of this study was to determine the effectiveness of high-fidelity simulation training of novice residents in the initial management of critical intraoperative events. METHODS Twenty-one novice residents part...
